So I just bought and downloaded the nik software suite a couple of days ago but noticed this problem almost immediatly after using silver efex. Whenever I adjust the structure bar, I get all these lines that appear in my photo. Not sure what's going on. Google turned up nothing. Anyone seen this before? I really like the software otherwise.

I had that issue when trying to run the program on my old macbook pro. It was just way under powered for the task. When i ran the same images via my mac pro or mac book pro retina Ive had no issues.

Many of these image processing engines work in terms of tiles. It looks like there is a bug in the underlying OpenGL/DirectX driver that is not rendering the border of the tiles correctly. Check if there is a driver update or see if you can swap out to a card with more mature drivers ? Are there any GPU rendering options that you can disable ?

I updated my graphics driver to the latest version and processed a few images with no more lines. Thanks so much!
